Its energy efficiency ratio (SEER) of 7.5 indicates moderate efficiency, balancing power use and cooling without being top-tier in energy savings.

Operating at about 50 decibels, this AC unit is relatively quiet for a truck air conditioner, contributing to a more pleasant driving and resting environment. Installation is easy, and the split system design helps improve airflow and heat dissipation, enhanced by a unique sun-shaped air outlet. The low noise function supports quiet operation when parked or driving with the engine off. Its size and weight are reasonable for the category but should be checked against space availability in the vehicle.

A key consideration is that the unit does not include refrigerant; users need to purchase and add R134a refrigerant separately. This process may require technical knowledge or professional assistance. The AC features standard controls, without advanced remote or smart features. This unit is a practical choice for truck drivers or operators seeking reliable cooling with straightforward installation, provided refrigerant charging is appropriately managed.

The Mieligo 12V Truck Air Conditioner offers 10,000 BTU cooling power, which is solid for providing comfortable temperatures inside semi-truck cabs and similar vehicles. It uses a DC inverter compressor, which is good for quickly adjusting cooling output and maintaining energy efficiency, helping to save power during use. The system is a split type with separate indoor and outdoor units, making it easier to install in trucks, trailers, and even equipment like cranes or RVs. It runs quietly at about 45 decibels, so it won’t add much noise to your cab environment. The brushless fan improves durability and keeps the noise low, which is helpful during long trips or parking.

A copper evaporator inside ensures efficient cooling, although this part can add to the cost.

Offering between 6800 to 10500 BTUs of cooling power, it promises fast and efficient cooling, making it suitable for larger vehicle cabins. One of its standout features is its low noise level, with the internal unit operating at 37 dB, ensuring a quiet environment for driving and sleeping. This is a significant advantage for long-haul drivers who need a peaceful resting environment.

The unit's energy efficiency ratio (EER) is relatively modest at 3.26, which might not be the best in the market but still provides a decent balance between performance and power consumption. However, it requires a robust power setup including a 12V 80AH or higher battery and a 1500W generator, which could be a consideration for some users. The installation is split-type, which generally allows for flexible placement but may require professional installation.

One potential drawback is that the unit does not come with refrigerant, meaning users need to purchase and add 550g of R134a refrigerant themselves, along with performing a vacuum treat. This could be an additional hassle for those who are not familiar with AC maintenance. Additionally, the unit includes modern conveniences like remote control for ease of use.
